Thank you, I have ran through the initial quote setup, while it said quotes have been enabled and it also updated each account it said it had been disabled on /home to prevent performance degradation... I'm assuming it's referring to the /home directory only and not the accounts under it?

The disk space usage is still reading 0mb or low for most accounts - I presume this would be until quotes are updated by the system? Is there a way I can force it manually? I'm not sure if fixquotas is the right task for this?
